Installation

Install from source:

pip install git+https://github.com/defipy-devs/blockscout-python.git

Alternatively, install from PyPI:

pip install blockscout-python

Basic Usage

from blockscout import Blockscout
from blockscout import Net
eth = Blockscout(Net.ROLLUX, API.RPC)  

Then you can call all available methods, e.g.:

eth.get_balance(address="0xBb8b9456F615545c88528653024E87C6069d1598")

> {'message': 'OK', 'result': '2010991698475838058402243', 'status': '1'}

Token Transfers: Time Series

• See test notebook for example

Pull data for specified address

from blockscout import TokenTransfers
from blockscout import Net

addr = '0x8A4AA176007196D48d39C89402d3753c39AE64c1'
tkn_trans = TokenTransfers(Net.ROLLUX)
dict_transfers = tkn_trans.apply(addr)
tkn_balances = tkn_trans.get_tkn_balances()
tkn_balances

OUTPUT:

{'USDT': {'tkn_balance': 89590009236, 'tkn_decimal': 6},
'USDC': {'tkn_balance': 238003477125, 'tkn_decimal': 6},
'ETH': {'tkn_balance': 2689089808644384766235, 'tkn_decimal': 18},
'BTC': {'tkn_balance': 999799972, 'tkn_decimal': 8},
'WSYS': {'tkn_balance': 65787771636449164370510, 'tkn_decimal': 18}}

Plot token transfers

import matplotlib.pyplot as plt

tkn_symbol = 'USDC' 
dates, tkn_coin_balances = tkn_trans.get_tkn_timeseries(dict_transfers, tkn_symbol)
fig, (TKN_ax) = plt.subplots(nrows=1, sharex=False, sharey=False, figsize=(16, 3))
TKN_ax.plot(dates, tkn_coin_balances, color = 'r',linestyle = 'dashdot', label=tkn_symbol) 
TKN_ax.set_ylabel(f'{tkn_symbol} Balance', size=14)
TKN_ax.set_xlabel('Date', size=14)

Coin Transfers: Time Series

• See test notebook for example

Pull data for specified address

from blockscout import CoinTransfers
from blockscout import Net

addr = '0x8A4AA176007196D48d39C89402d3753c39AE64c1'
coin_trans = CoinTransfers(Net.ROLLUX)
txs = coin_trans.pull_coin_transactions(addr)
coin_tx = coin_trans.pull_coin_balances(addr, txs)

Plot token transfers

import matplotlib.pyplot as plt

tkn_symbol = 'SYS' 
dates, tkn_coin_balances = coin_trans.get_tkn_timeseries(coin_tx)
fig, (TKN_ax) = plt.subplots(nrows=1, sharex=False, sharey=False, figsize=(16, 3))
TKN_ax.plot(dates, tkn_coin_balances, color = 'r',linestyle = 'dashdot', label=tkn_symbol) 
TKN_ax.set_ylabel(f'{tkn_symbol} Balance', size=14)
TKN_ax.set_xlabel('Date', size=14)
